Benefits of technology

The structure maintains a uniform pleated appearance from top to bottom when fully extended, reducing material waste and enabling full extension of all cells for consistent shading and aesthetic appeal, while allowing flexibility in material choice for different effects.

Problems solved by technology

One shortcoming experienced with standard honeycomb shade constructions that results in an undesired aesthetic appearance is due to the way honeycomb shades achieve their shape.
Because the structure of the honeycomb structure is based on the spring coefficient of the material, however, the overall appearance of a conventional honeycomb panel is affected by the varying amount of weight supported by any particular cell of the honeycomb panel.
Thus, the cellular structure will fail to provide a uniformly distributed pleated appearance.
The result of this is an uneven appearance and uneven shading ability of the blind.
Over time, the cells towards the top of a shade may also be stretched such that the material loses its ability to retain a creased or pleated appearance.
The inability of a typical honeycomb cellular structure to limit the extent particular cells may be stretched also results in a waste of material.
As a result, the material costs of providing additional rows of honeycomb cells than would otherwise be necessary to cover a window are increased.
This lack of flexibility in the ability to choose from different fabrics to provide different coloring, shading, and insulation combinations is simply not possible with shades constructed from a single type of material.

Abstract

A cellular structure such as a honeycomb window treatment comprises a plurality of rows of elongated cells secured to one another. Each of the rows is constructed by providing a first longitudinally extending length of material, which includes a first surface and a second surface, as well as, a lesser width portion and a greater width portion. A second length of material is also provided that includes a first surface and a second surface. The second surface of the second material is secured to the first surface over the greater width portion of the first material along a plurality longitudinally extending locations on the second surface of the second material to form a row. A longitudinally extending crease is also formed in the first material such that the lesser width portion and the greater width portion of the first material lie on opposite sides of the crease.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of application Ser. No. 10 / 281,561, filed Oct. 28, 2002 now U.S. Pat. No. 6,898,066 by Fu-Lai Yu, which is hereby incorporated by reference.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates to an expandable cellular structure such as used in honeycomb window shades, having a plurality of parallel elongated cells.BACKGROUND OF THE INVENTION[0003]Expandable cellular structures that are often used as honeycomb window shades consisting of a plurality of elongated tubular cells are well known in the art. Honeycomb window shades provide consumers with numerous advantages in window coverings such as improved insulation, light filtering, and aesthetic appeal. The present invention relates to cellular structures and a method for making the cellular structures that utilizes a novel system of cutting, folding, gluing and arranging strips of fabric material in the construction of honeycomb panels.[00...
